Aluminium Steel Coils

Aluminium Steel Coils

Aluminum coils can be produced from aluminum ingots or other forms of raw aluminum (called cold rolling or direct casting) or from a smelting process directly through rolling (called continuous casting). These sheets of rolled aluminum are then rolled up, or coiled, around a core. Our aluminum coils are precision-finished to match international standards. They have good shape, high tolerance, versatility, and blemish-free surfaces. They are used in commercial and general engineering applications such as bus bodies, cladding, and fan blades. The company meets the demands of its ever-growing clientele with continuous upgrades and process improvements.
